He has had it in for the daughter of a friend for over a year. Have spoken to preschool 3 times. No issue at preschool. it happens at social events. He gets punished... i.e. taken away immediately. The girls mother confronted me yesterday... Shouting and insulting my son. I'm aFraid the friendship is over... But the issue of hitting little girls remains. I can't get to the bottom of it. Help!!!!
